I totally understand the confusion of the scant 1/4 inch. I just bought a new Bernina and the lady told me to leave the needle in place as is and not to move it over but its not my "old" 1/4" as in my old machine so I'm moving the needle over anyway. I did the test and it came out right with it moved over....however its aggravating to have to do that since the machine came with the 1/4" foot that isn't really....ugh!!!!
